Want to go higher tech on the old garage door, but don't know much about the so-called "commercial grade" garage door openers, advice is welcome!
Thanks,
Just a stronger opener basically. Able to lift the heavier commerical doors. I have one on my 8' x 18' door. Looks like a basic door opener, just heavier duty. Some are much heavier with pully and chains and cost big $$$$.
